Brewing White Tea... Help!

Hi,
I have a silly question, but I am drinking alot of White tea, all different, and have a question regarding brewing. It appears that my white teas are much darker when brewed than I guess they are supposed to be. I brew my tea for 2-3 minutes, yet I continually see that my "White" tea appears as dark as my "Black" teas. Is this normal ? I thought white teas should be very very light in color when brewed.

White tea is strange brew...white peony, aka bai mudan (and several other spellings) often gets darker when just sitting in my cup. White Peony and similar whites can brew darker than say silver needles that should never brew up dark.

T-Ching had a post just today that was sort of related to this issue. Since I know hardly anything about white teas, I found it pretty interesting and it convinced me that I know even less than I thought I did!
